Connector

Abstract

A connector including a casing, a base, a rear plug, a plurality of first terminals, a plurality of second terminals, a middle shielding, an upper shielding and a lower shielding. The base is disposed in the casing and includes an upper portion, a middle portion and a lower portion. The rear plug is disposed at a side of the lower portion. The first terminals are insert molded on the upper portion. Each of the second terminals includes a first portion and a second portion that are connected in a bent manner. The first portions are insert molded on the lower portion, and the second portions are insert molded on the rear plug. The middle shielding passes through the middle portion and is disposed between the first terminals and the second terminals. The upper shielding and the lower shielding are fixed to the base.

What is claimed is: 
     
       1. A connector, comprising:
 a casing; 
 a base, disposed in the casing and comprises an upper portion, a middle portion and, a lower portion; 
 a rear plug, disposed at a side of the lower portion; 
 a plurality of first terminals, insert molded on the upper portion; 
 a plurality of second terminals, each of the second terminals comprising a first portion and a second portion that are connected in a bent manner, wherein the first portions are insert molded on the lower portion, and the second portions are insert molded on the rear plug; 
 a middle shielding, passing through the middle portion and disposed between the first terminals and the second terminals; 
 an upper shielding, fixed to the base and disposed at a side of the upper portion; and 
 a lower shielding, fixed to the base and disposed at a side of the lower portion, wherein the lower portion comprises at least one first engagement portion, and the rear plug comprises at least one second engagement portion detachably engaged with the at least one first engagement portion, the lower portion and the rear plug are two members independent from each other. 
 
     
     
       2. The connector as described in  claim 1 , wherein the upper portion has a surface away from the middle portion, and the surface has at least one depression, such that the upper portion has different thicknesses. 
     
     
       3. The connector as described in  claim 2 , wherein the upper shielding comprises a first upper shielding portion and a second upper shielding portion connected to the first upper shielding portion in a bent manner, wherein when the connector is docked with a docking connector, the first upper shielding portion contacts the docking connector, the second upper shielding portion abuts the casing, the at least one depression comprises a first upper depression, the upper portion comprises an upper portion main body and an upper portion extension, the first upper depression is formed on the upper portion extension such that a thickness of the upper portion extension is smaller than a thickness of the upper portion main body, wherein the first upper shielding portion is disposed at the upper portion extension and disposed in the first upper depression. 
     
     
       4. The connector as described in  claim 3 , wherein the at least one depression comprises a second upper depression formed in the upper portion main body. 
     
     
       5. The connector as described in  claim 1 , wherein the lower portion has a surface away from the middle portion, and the surface has at least one depression, such that the lower portion has different thicknesses. 
     
     
       6. The connector as described in  claim 5 , wherein the lower shielding comprises a first lower shielding portion and a second lower shielding portion connected to the first lower shielding portion in a bent manner, wherein when the connector is docked with a docking connector, the first lower shielding portion contacts the docking connector, the second lower shielding portion abuts the casing, the at least one depression comprises a first lower depression, the lower portion comprises a lower portion main body and a lower portion extension, the first lower depression is formed on the lower portion extension such that a thickness of the lower portion extension is smaller than a thickness of the lower portion main body, wherein the first lower shielding portion is disposed at the lower portion extension and located in the first lower depression. 
     
     
       7. The connector as described in  claim 6 , wherein the at least one depression comprises a second lower depression formed in the lower portion main body. 
     
     
       8. The connector as described in  claim 1 , wherein the middle portion comprises at least one assembly hole, and the lower portion is inserted into at least one assembly of the at least one assembly hole. 
     
     
       9. The connector as described in  claim 1 , wherein the middle portion comprises at least one assembly portion, the upper shielding comprises at least one support arm engaged with the at least one assembly portion, and the lower shielding comprises at least one second support arm engaged with the at least one assembly portion.
